What causes write protection on SanDisk portable SSD on Mac?

The following are some common causes of your SanDisk portable SSD becoming write-protected:

• The file system of the SanDisk portable SSD is NTFS which is not compatible with macOS: Windows and Mac computers use different file systems. Mac computers do not support the NTFS file system, which Windows uses. Additionally, NTFS and FAT32/ExFAT are used by the vast majority of USB flash drives, pens, Micro SD cards, and SSD drives. As a result, you can see an error message saying that the storage device is write-protected if you try to use it on a Mac.
• The write-protect toggle has been turned on: The "write protected" toggle has been locked. Remember that some flash drives and SD cards have a switch that allows you to toggle the write-protection feature on and off. Check to see if the lock is unlocked.
• Malware/virus infection: Malware infects a SanDisk flash drive, memory card, or solid-state drive. If you suspect that you have a virus, please scan your system with anti-virus software.
• Enabling BitLocker for secure storage: The value of the key in the Windows registry is incorrect.
• This SSD drive is at capacity: All the space on your SanDisk drives has been used up. If the issue persists, you should verify and back up your files somewhere secure, clear off some space, and then verify again.

This error message occurs for various reasons, but these are the most typical. Let's learn about effective methods for disabling write protection on a SanDisk Portable SSD.
